A frz'rezzf WM V 4 APPARATUS FOR ACTUATING FLUIISS.

To all whom it may mm.-

, Be it known that I, RUDoLrH CONRADEI t, I

a citizen of the United States, residing at Erie, in "the county of Eriev and State of Pennsylvania, have invented certain new and useful Improvements-in Apparatus for Actuating Fluids; and I do hereby declare the following to be a full, clear, and exact descri 'tion of the invention, such aswill enab e others skilled in the art-to which it appertains to makeand use the same.

Thisinvention relates to apparatuses for actuating fluids under pressure and consists in certain im rovements' in theconstruction thereof as will be hereinafter fully described and pointed out in the'claims.

More particularly, my invention relates to that class offluid actuating devices wherein a motor is used to actuate another fluid by the d rect contact of the actuating and actuated fluids, the actuating and actuated 'fluids having different properties, especially as to specific gravity, so as to prevent the mixing of the fluids to any-great extent.

In carrying out my invention, I admit the quantity of fluid to be actuated to a lift, that is,'the pipeor passage through which the fluid is to beforced. I then subject it to the pressure ofthe actuating fluid anddrive the-column of fluid 'to be actuated to the desired oint of'admission, This, in a general way, as been accomplished heretofore but with A my device, I have arranged means whereby the length ofthe column maybe-regulated in order that a uniform pressure will actuate it. In carrying out my invention, I further utilize the expansive force of the actuating fluid to-fill the clearance fora second operation, preferably in a-secondpumping apparatus.

In carrying out my inventlon, I havealso arranged automatic meansfor cont-rolling the raised by the apparatus actuating fluid so as to accomplish an intermittent action automatically.-

" I have also arranged mechanisms whereby 'the'columns of fluid actuated may be by the.

same actuating fluid, positively acted upon to further convey the actuated fluid. f

In carrying out my invention, where ap-' lied to 011 wells, I have arranged a mechanlsm whereby the actuated fluid is gas, preferably'from'the well, from which the ofil is-being My mvention also includes the devices hereinafter described in the claims.

Fig. 11, is a side elevation of a cam actuated rock arm;

A, marks the umpchamber in which. there is the usual perforated intake pipe. Extending from the pum chamber. A. is the pipe,,B, which extends rom said chamber,

ordinarily, to the top of the well. Thepipe,- C, connects the chamber, A, with theactuat ,ing fluid supply. The pipe, B, extends downinto the chamber, A, and is provided with a valve seat, '6, on its lower end. A

valve, a, is arranged to be seated onthe seat, I). Extendin from the valve, a, is a stem, 0/, on 'WlllOh 1s a head, a The head, a, 1s

; en aged by a cage, 03, extending from a va ve, a The stem,. a, operating in the cage, (1 gives to the valves, a, and m, a slight relative movement. -The valve, a is arrangedto be seated on a seat, of, ,at the bottom of-the chamber, A, and to. close a passage, a*, into the-intake pi e, A.

The lower end of the pipe, C, is provided with alseatingsurface, a, so that the C, may be closed by a float valve, a float valve, a, is held in place by the cage, 03. The valve, a, is preferably buoyant enough to just float the valves, a and a. The device, however, would o erate under ordinary pressures without suc buoyancy. .The operation of this part of the device is as follows: The oil enters the intake, A, passes through thepassage, a, lifts the valve, (1*, and in lifting the valve, (1*, seats the valve;a. Oil continues to enter until it fills the chamber, A. The valve, a", prevents a movement of the oil into the supply pipe, and

The

I seat, a", is arranged on a curve bottom, a.

ittthe valve, a, prevents the entrance of the oil into the pipe, B. In this way, the amount of oil admitted each time is equalto ust the capacity of the chamber, A. The actuating fluid supply is then turned on and through seat, I), and the valve, a is in its uppermost position, there is quite an open space between the bottom, a and the valve, a. As soon as the intake movement has ceased, the valve,-a drops back into the more contracted part of the bottom, a so that as the pressure is turned onto the liquid, it creates allow the outflow of the liquid. this passage is a balance valve, D. This an outward movement by the valve, (1,, and pressure is created on the valve, a sufficiently to draw the valve, (1, from its seat. The valve, a, is thus immediately seated and held on its seat by the pressure. The

liquid from the chamber, A, is then forced through the pipe, B, until the end of the pipe, B, is exposed. The amount of liquid K in the pipe, B, forms what is usually termed the slug and this is followed by the actuating fluid and raised in-the form of this column or slug to the top of the well.

It will be noted that as the column or slug is lifted to the surface, the entire pipe, B, as well as the supplypipe, which in the ordinary practice, may reach several thousand feet, are filled with actuating fluid at the supply ressure. It must be apparent of course, t at if this is immediately exhausted, that great waste of ower takes lace. order ,=to overcome t is largely, have arranged a plurality of pumping apparatuses,

as shown, two apparatuses, each in a differ- I have also arranged a mechanlsrn ent well. so that after the column or slug has been raised and discharged, the actuating fluid is trapped to prevent it from escaping and is then conveyed to the supply pipe of the second well, so that the clearance in the supply pipe of the second well is filled in this manner. After filling this clearance, I preferably convey the remainder of the actuating fluid remaining in the first well to' the intake of the compressor. I have heretofore utilized the compounding of actuating fluid in apparatuses for actuating fluids as shown in my patent dated Se tember 18th, 1900, No. 657,917, and also utilized insuchapparatuses the increase of pressure after the movement of the actuating fluid for reversing the valve, as indicated in said patent.

I trap the actuating fluid after the discharge of the oil'in the following manner:

. (See Figs. 1 and 3.) The oil is carried by the pipe, B, through the passa e, b, tothe trap chamber, D. A passage, is arranged to Controlling valve is arranged in a double diaphragm, d, with the method ordinarily used in throttlinggovernors. Extending from the valve D is a stem, (1, and extending from this stem is a float, D A assage, (Z is arranged at the upper end of the trap and extending into the trap from this passage is a cage, (1 A valve, D, is arran ed in the cage and adapted to be seated on the seat, (i over the passage, d. The stem, (1 of the valve, D, just contacts the float, D when in its lower position, and the valve, D closed. As soon as the liquid reaches the trap through'the passage, vb, from the pi e, B, it carries up with it the float, D an .o ens the valve, D With the .in rush of the uid, the float, D is carried up a suflicient ilistance to seat the valve, D and the liquid then passes out through the passage, b There is however, a sufficient pressure maintained in the trap chamber, .D, increasing of course, as the length of the column or slug decreases in the pi e,

D. This pressure maintains the valve,

so that where no further mechanism. for trapping the air is provided as for instance when the pump F is not used and the connection 0 closed the valves D and D will remain closed until the air pressure is so reduced as to permit them to act, the closure allowing the increase in pressure necessary to actuate the valve mechanism as' hereinafter described.

It is desirable in oil wells to separate the water from the oil. This is done in the separator, E, which is of the usual construction. If it is desired to convey the oil or actuated fluid a greater distance, the actuating fluid, which has raised the column or slug and deposited it in the separator, E, may be utilized or this purpose. I show a mechanism for accomplishingthis purpose, as follows: (See Figs. 1 and 4.) Extending from the separator, E, is apipe, B. This enters a chamber, F, through an intake assa e, f. The intake assage is controlled y a c eck valve, f, and is separated from the main pump chamber, F, by a diaphragm, f. A passage, f extends through the dia hragm,'f .The eduction pi e, B extends om below the diaphragm, 7 out of the chamber. Arranged in the e uction pipe is a check valve, f and arranged over the passage, f, is a float and check valve, f A passage, 0 is arranged in the end of the trap chamber, D,

and connects with a ipe, C, which passes the actuating fluid under pressure, passes throu h'the passage, and ipe, C, into the cham fl er, F, the chamber, F, having been filled by gravity from the separator, E. The chamber, F, is referably of sufficient size to accommodate tffe oil raised in one slug. The sup ly' pressure on the upper surface of the oil orces it down through the passage, f, u

through the eduction pipe, B past the chec valve, f As soon as the oil reaches the bottom of the chamber, F, the actuating fluid is trapped and further action is prevented by the seating of the float valve, f During the outflow of-the fluid from the chamber, F, a

' back movement from the chamber to the pipe, B is prevented by the check valve, f, and after the completion of the operation and the reduction of pressure in the chamber, F,

B is revented by the check valve, f It is desira le that these movements should be accomplished automatically. I carry this out by providing a valve mechanism which a return movement from the eduction pipe,

will reverse only when themaximum supply pressure is brought into action in the pipe, C. t will be noted that after forcing up the slug and conveying the oil from the chamber, F, the actuating fluid is trapped both by the trap, D, and the ump, F, so that the pressure of this fluid rlses to the full supply pressure. This rise in pressure due .to the trapping of the actuating fluid just described, is arranged in my device to actuate the valve mechanism. When the pum Fis not used the opening 0 is closed and t e trap D then effects in itself. the trapping of the air.

The valve mechanism is as follows: A valve body,'G,-has the supply chambers, G

Fhese chambers are incommunication yvith the chambers, G G throu h the passages g g. The chambers, G G term, for

convenience, the equalizing chambers. They are connected by a passage, g-. Adjacent to the equalizing chambers are the'exhaust chambers, G, G. These are connected with the equalizing chambers by passa es, g g A supply pipe, 0?, is connected wit the passages, c -c entering the supply chambers, G G The ipes, 0, one ineach Well, are connected wit the the equalizing cham ers, G G The exhaust passages, c -c, lead from the exhaust chambers, G"G*, preferably through a pipe, C", to the intake of the compressor, J, so that the compressor produces suction on the chamber exhausted. The su p1 valves, g g which are referably of t I e check valve type, cover t e passages, g-g. The equalizm valve, g, covers a passage, 9, the exhaust valves, g 9 cover the assages, g 9 All of these valves are 51ml ar in shape and are normally crowded to their seats by the springs g". Adjacent to the supply chambers; G G are the motor valve chambers,

G G From these chambers extend the passages, 11, i which lead through the pipes,

assages, cc, entering i, 2', to the motor 0 crating the various valves. The chambers, G are connected with the su ply chambers by the passages, g' j The va ves, g, close these passages and the springs, g, tend to normally seat these valves.

The operation of the valve mechanism in relation to the pumping apparatus is as follows: Starting with the mam valves closed, the ex ansive force of theactuating fluid on the va ve motor opens one of the valves,g and one of the valves, g. It also opens the exhaust valve, g operating on the opposite well. The motor is so arranged that it will not operate in a reverse direction except when a maximum pressure is brought to bear upon it, and as there is a ready outflow for sure in the supply chamber, is kept below this maximum ressure until the slug is raised and the uid is conveyedfrom the pump chamber, F. After the conclusion of the o eration of the trap, D, and pump, F, and the trap ing of the actuating fluid therein, the supp y pressure of course reaches its maximum, and this acting through the passage, 9 operates upon the motor to permit the closing of the valve, 9 and the exhaust valve, g that is open. A slight advance movement of the motor opens the equalizing valve, 9 The equalizing valve is maintained in an open position a sufficient length of time topermit the actuating fluid to pass from the first well, where it in under ressure,

into the supplypipes of the secon Well, so.

that thepressure in the two wells may be equalized. A further movement of the mo tor permits the closing of the equalizing valve and then as a last movement of the motorin that direction, permits the closing of the open valve, g. The expansive force of the actuating fluid on the motor, as well as a weight device hereinafter described, carries the motor forward so as toopen the supply valve, g motor valve, g, and exhaust valve, 9 for the opposite wellfrom the one first o ened. This completes the cycle of operation and it will be noted that there are two pum ing systems and that the valve connects the rst of said systems with the supply, cuts ofl' said supply, connects the systems, exhausts the supply from the first system and turns on the supply in the second system to supplement the pressure admitted to the second system through the compounding operation.

1" preferably inake the equalizing valve balanced. This, I do by placing the valve plunmeets the cylinder,- g, with the chamber, G

qplposite the one occupied by the valve. e plunger g is approximately the size of the passage, g so that when pressure is in the chamber opposite the one occupied by the valve, the ressure on both sides of the valve is practica y the same and when the ressure is in the side occupied by the valve, t e plun ger, g prevents a top pressure on the valve, so that the valve is practically balanced with pressure in either chamber.

The mechanism for operating the several valves is as follows: Immediately at the side of the valve body is a frame, H, to which the valve body is attached. Arranged in this frame are the journal bushings, H and journaled in these bushings is the rod, H Keyed on the rod or shaft, H is the cam cylinder, H Journaled on the exterior of the bushing, H are the cam rings, H The cam cylinder is provided with a gear, H, which meshes a rack, I. with a motor, which as before described, operates only with a maximum pressure at the times mentioned. When the motor starts, it moves forward, turns the cam cylinder, and when reversed, it turns the cam cylinder in the opposite direction. Arrangedon the cam cylinder are the cams, b, one at each side of the cam cylinder, and arranged in the paths of the stems, g", g, of the supply valves,

* arranged the shoulders-or pins, h.

g 9 These cams, h, are arranged so that they lift one of the valves, 9 just as the cylinder reaches its extreme position. The cam cylinder is also provided with two cams, h the paths of which pass the stems, g 9 of the exhaust valves, g g These are arranged in line with the cams, h, one of the cams, h being arranged to open the exhaust valve opposite the supply valve opened by the cam, h, in line with which it is. Also arranged on the cylinder,-H is the equalizing cam if, its path being such as to operate upon the stem, 9 of the equalizing valve, 9. The equalizing cam, h is of considerable length,

the extreme ends .being just inside of the cams h and h so that the supply and exhaust valveshave dropped off the cams, h and h before the cam k reaches the stem of the equalizing valve. In order that the motor may continue its operation without closing the motor valves, g", 9, some mechanism must be provided which will permit this movement and still make the valve, 9, subject to the action of the motor. I accomplish this by providing the rings, H These rings are provided with the grooves, if, in which are A. pin, it", is secured to the cylinder, H, and is free to move in the groove, it, except when in contact with a shoulder, k The mechanism operates somewhat in the manner of the tumblers of a combination lock. The pin, h, contacts the shoulder, h so as to bring the cam, h, in line with the adjacent cam, h, just before the cam, it, reaches the stem of the supply valve. Of course, when the pin, 'h", reaches this shoulder, it the ring, H is The rack, I,is connected.

- valves, '5 i locked with the cylinder, H, so that 'the cams, h and h, lift the supply'valve and motor valve together. When the maximum pressure is reached and the motor isleversed, the cams hand h are of course, immediately actuated with the cam cylinder, as well as the equalizing cam, 71. The cam, h, however, being arranged on the ring, H and the ring, H being carried by separate bearings from that in which the cylinder, H, moves,-

remains stationary until the pin, h, in its backward movement reaches the rear shoulder, h This takes place just as the end of the equalizing cam passes from under the stem of the equalizing valve and just before the cams, h and h, of the opposite side of the valve mechanism, pass under thestems of their respective valves so that the motor valve controlling the motor 'in the movement of its direction is closed just before the end of the stroke of the motor. In order that there may be no side strains. on the valve stems, I provide the rock arms, h. These arms are pivoted on a plate, hf, and are provided with a roller, If. These rollers operate upon the cams, h, h, k and h and the rock arms communicate the motion to the valve stems.

The motor for actuating the valve is as follows: Screwed into the opposite sides of the frame, H, are the cylinders, 1 Arranged in these cylinders are the pistons, I and connecting these pistons is the rack, I. The passages, 'i, 4/, lead from the chambers, G G and pass by the pipes, 'i, into the oil reservoirs, I. The oil reservoirs are connected with the cylinder throu h the needle A liquid, prefera 1y oil, is arranged in the reservoirs, I. I utilizing oil is for convenience in that it is easier to form a tight joint between the cylinders, I and the pistons, I Arranged on the end of the shaft, H is an arm, H weight, H is fixed on this arm by means of asset screw, H The weight may be adjusted by means of the set screw so as to lengthen or shorten the arm. The arm is in a horizontal-position at the extreme ends of the stroke of the piston. justed on the arm so as to require the maximum pressure of the actuating fluid upon the ends of the piston arranged to raise the weight before any movement of the motor cam takes place. As soon as this maximum pressure is reached, as heretofore described, the air or gas operating upon the oil and indirectly upon the piston starts the motor and moves the cam cylinder, as heretoforedescribed. In order that a sufficient time may elapse for the actuating fluid in one apparatus to pass from that apparatus to another so as to equalize the pressure in the two during the time that the equalizing cam is under the equalizing valve, or in other "words, during a movement of the -motor, I

The purpose of The weight is adprovide the needle valves, i By reducing the area of the passage by the needle valve, the speed in the motor may be decreased, or by enlarging this passage, the speed of the motor may be increased so as to adjust it for this purpose. In order to provide an exhaust for the actuating fluid after a movement of the motor, I provide the valves, '5 i openings and the actuating fluid is exhaust+ ed through this minute opening. This taking place during the entire time of the movement of the actuating fluid into the apparatus, ordinarily precedes 'the time of the initial movement of the motor. The exhaust of course, may becompleted after the motor starts in a reverse direction, but ordinarily the entire exhaust would have taken place before the reverse. v

It has been found in practice that the contact of air with oil has a tendency to separate the paraflin from the *oil, and this taking place in the well, operates to choke the well.

In order to overcome this objection in apparatuses using gaseous actuatingwfluids, I prefer to utilize a gas for that purpose and preferably natural gas from the well. I therefore connect the well casing through the pipes, K, K, with the intake, C of the compressor. l/Vhere a group of wells are pumped by the apparatus, all of these may be connected with the intake of the compressor, and preferably each well is provided with a check valve, 1c. Where the exhaust from the well is directed to the intake of the,

compressor, as shown in the drawings, there is of coure, very little waste of the actuating fluid and it is utilized over and over again. When, however, the supply of actuating fluid falls below normal, a fresh supply may be had from the well through the check valves. Thus, the wells are not subjected at any time to an increased pressure which tends to check the flow of oil into the well and on the other hand, a ready supply is always at hand as an actuating fluid.

I have shown in-my co-pending application filed Dec. 24, 1902, No. 136,431, a pres- :sure device controlling the admission of actuating fluid to the pump chamber; with means actuated with the pressure in said chamber for controlling the pressure device and do not claim in this application-the construction claimed therein.
